"We need 200,000 to 250,000 jobs to really make this, or to illustrate that this is a healthy and strongish recovery," Altman, chairman and founder of Evercore Partners, said in an interview on Bloomberg Television. "We're nowhere near that."

U.S. markets reacted by sending stocks sharply lower on the open. The Dow was down more than 175 points by 12:45 p.m. EDT.

Recent labor market indicators prior to Friday's jobs report reflected notably slower labor demand growth and shorter work weeks. While employment growth continued in April, it did so at a markedly slower pace than in prior months.

Just 19% of firms reported hiring new workers, while 7% reported layoffs. In addition, the hours worked index dropped eight points to a negative 4.6, its first negative reading in eight months.

On Wednesday, payroll processor ADP's monthly report revealed that the private sector only added a paltry 119,000 jobs in April, appreciably below the 170,000 forecast, and the smallest gain since September 2011.

Employers also have gotten more adept at squeezing more manpower out of fewer workers over shorter hours. Hiring will only pick up when increased demand forces them to do so.

Lackluster U.S. Economic Data
April's U.S. jobs report is the latest in a string of data that's not making anyone feel optimistic about the U.S. economy.

The uninspiring numbers came on the heels of last week's report on gross domestic product, which showed a steep drop in spending by businesses and government. The U.S. economy grew at an estimated pace of 2.2% in the first quarter of the year, according to the U.S. Commerce Department, a drop from 3% in the fourth quarter.

The GDP report is just another reason why companies are not adding to their workforce.

The Commerce Department revealed this week that consumer income ticked up 0.4% in March, while spending increased by 0.3%. But those numbers aren't as encouraging when you consider much of the spending increase resulted from higher gasoline prices.

When adjusted for inflation, spending eked up a measly 0.1%.

Despite the less-the-stellar numbers from various economic sectors, economists maintain the U.S. recovery will continue. But, they add, the economy is not showing much muscle.

Economists polled by The Associated Press expect growth to pick up this year, but not enough to make much of a dent in the high unemployment rate.

In a speech Thursday, John Williams, president of the Federal Reserve Bank of San Francisco said, "The outlook is for continued moderate growth. Nonetheless, we have nearly 4 &frac12; million fewer jobs today than five years ago."

While the overall U.S. economy and employment levels are better than they were at the start of the Great Recession, they still have miles to go before investors and economists breathe a sigh of relief.
